First, when the search request transmitting unit 21 provided in the client terminal 2 transmits the search request 31 (S41), the search request receiving unit 11 receives the search request 31 (S42).
[0031]
A token is extracted from the received search request 31 (S43), and a character string indicating “content ID” (FIG. 3) existing at a predetermined position in the packet is obtained as a search key 32, and the packet is acquired. A character string indicating the “user ID” (FIG. 4) existing at a predetermined position in is obtained as the user identifier 35. At the same time, based on the TCP / IP packet header 33 of the search request 31, the source IP address is acquired as the IP address 34.
[0032]
The search key 32 is sent to the content URL search unit 12 (S44), and the user identifier 35 and the IP address 34 are sent to the user attribute determination unit 14 (S45, S46).
[0033]
The content URL search unit 12 receives the search key 32 (S47), and searches the content attribute database 13 shown in FIG. 3 for a content attribute based on the received search key 32 (S48). The content attribute information 37 covering a plurality of columns including the content URL 36 of the record is acquired (S49).
[0034]
Here, it is assumed that the content URL 36 stored in the content attribute database 13 is a virtual URL described according to a predetermined format. Therefore, a virtual URL can be obtained based on the search key.
[0035]
It is sufficient that the content URL search unit 12 acquires the content attribute information 37 (S49), and acquires the two columns of “content URL” and “providing target area” shown in FIG. is there. The acquired content attribute information 37 is sent to the URL conversion unit 17 (S410).
[0036]
On the other hand, the user attribute determining unit 14 receives the user identifier 35 (S411) and receives the IP address (S412).
